T 0 all whom 'it may concern:

Be it known that I, GEORGE W. WINTERS, citizen of the United States,residing at De Queen, in the county of Sevier and State of Arkansas,have invented certain new and useful Improvements in Carbureters, ofwhich the following is a specification.

This invention relates to a carbureter, and has for its object toprovide a carbureter with a needle valve arranged to move with relationto its seat as the air and gas which f passes through the carbureter isthrottled,

whereby the proportion of liquid which passes through the seat of theneedle valve is automatically regulated at the time the air and gaspassageway through the carbureter is regulated.

A further object of the invention is to provide within the carbureter anair and gas discharge nozzle which is flattened and above and belowwhich are located air and gas passageways having discharge outletsdisposed in the same general direction as the outlet of the nozzle sothat the fluid which passes through the nozzle is enveloped in the Huidwhich passes through the said passageways.

Another object of the invention is to provide in a carbureter two meansfor carbureting the air, the said means being so arranged that theirmixtures are int-ermiXed as they pass from the carbureter, whereby theresultant miXture is highly carbureted and is in condition to createprompt and positive eX- plosions.

In the accompanying drawings Figure 1 is a vertical sectional view ofthe carbureter; Fig. 2 is a vertical sectional view of the carbureter,taken at a right angle to the view illustrated in Fig. 1; Fig. 3 is ahorizontal sectional view of the carbureter, cut on the line 3-3 of Fig.1; Fig. 4 is a horizontal sectional view of the carbureter, cut on theline4-4 of Fig. l; Fig. 5 is a horizontal sectional View of thecarbureter, cut on the line 5 5 of Fig. 2; Fig. 6 is a perspective viewof the ring and diaphragm used in the carbureter; Fig. 7 is aperspective view of the valve mechanism used in the carbureter forcontrolling the flow of gasolene; Fig'. 8 is a side elevation of amodied form of device for adjusting the needle valve with relation tothe cylinder; and Fig. 9 is a plan view of the means for limiting theadjustment of the parts.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

The carbureter consists of a body 1 which is provided at one side withan air inlet passageway 2, and at its diametrically opposite side with amixture discharge passageway 3. The upper end ofl the body 1 is closedby a cap 4, and the lower end thereof is closed by a cup 5. An innertube 6is held in stationary position within the body 1 and is centrallyand vertically disposed therein. The said tube is provided in thevicinity of its lower end and at its opposite sides with ports 7. Asleeve8 is journaled upon the tube 6 and is provided in the vicinity ofits lower end with ports 9 which at times are adapted to register withthe ports 7 in the tube 6. A bushing 10 is located in the lower end ofthe tube 6 and carries a vertically disposed tube 11 which is providedat its upper end with a valve seat 12. A chamber 13 slidably fits withinthe lower end of the body 1 and is held against rotation by means ofspaced lugs 14 which receive shoulders 15 formed within the lower end ofthe body 1.

The tube 11 projects down into and through the bottom of the chamber 13.A float 16 is located withinthe chamber 13 and is slidably mounted uponthe tube 11. An arm 17 is carried by the float 16, and the stem 18 of avalve 19 passes through the end portion of the said arm 17. A stop 20 ismounted upon the valve stem 18 and at times is engaged by the arm 17when the float'16 rises in the chamber 13, whereby the valve 19 is movedtoward a seat 21 provided in the shoulder 15 and is adapted to close aport 22 provided in the body 1 and which at its upper end communicateswith the interior of a nipple to be described later. lA ring 23 is heldagainst rotation in the body 1 and is provided at its upper end with adiaphragm 24 which in turn is provided with a central opening 25 whichis spaced from the outer periphery of the tube 8. The diaphragm 24 isalso provided with openings 26. A ring 27 is adjustably mounted upon,the tube 8 and is located over the opening 25 in the diaphragm 24. Thering 23 is provided at the upper portion of its edge with a camextension 28. A cylinder 29 is journaled in the upper portion of thebody 1 and is fixed at its top to the sleeve 8. The said cylinder isprovided at its lower end with a cam portion Y30 which is adapted toride upon the cam portion 28 of the ring 23, whereby the cylinder 29 ismoved slightly longitudinally as it is turned within the body 1.

At a point between the upper and lower ends of the cylinder 29, the tube6 is provided with a port 31, and at a point between the upper and lowerendsl of said cylinder, the tube 8 is provided with a port 32. The ports31 and 32 register at intervals. The cylinder 29 is provided with aninlet port 33 which is adapted at times to register with the inletpassageway 2 of the body 1 and at its diametrically7 opposite side thecylinder 29 is provided with an outlet passageway 34 which is adapted attimes to register with the outlet passageway 3. A nozzle 35 is locatedover the port 32 and is provided with a flattened discharge end whichprojects through the outlet port 34 and which is in the forinV of an arccoincident with the arc of curvature of the outer periphery of thecylinder 29. A spring 36 is interposed between the top of the cylinder29 and a packing box gland 37 located inthe cap 4. The said spring 36 isunder tension with a tendency to hold the cylinder 29 down against theupper edge Vof the ring 23. A plug'38 is adjustably screw threaded inthe upper end. of the sleeve 8 and is provided in its sides with slits39 which render the portions of the said plug that are inserted in thesleeve 8 flexible or movable with relation to each other and also serveas openings through which air may pass down through the said plug. Aneedle valve stem 40 is fixed to the plug, and the said stem projectsdown into the tube 6 and carries a flared valve head 41 which is adaptedto move toward and away from the seat 12 formed at the upper Vendof thetube 11. The head 41 is provided with a downwardly extending nose 42which projects down into the tube 11 and prevents the same from chokingup with sediment or viscous oil.

A split ring 43 is clamped upon the upper projecting portion 1f carriedbythe cap 4Yof the body 1. Thisk ring is illustrated ink detail in Fig.V9 and its end portions are held together by Ymeans of a clamp bolt 43,and the ring is provided with abutment arms 43 one of whichis providedwith an adjustable screw 43. A cap 44 is mounted upon the upper end ofthe sleeve 8 and the lower end of an air pipe 45 is connected to thesaid cap, and the upper end of said pipe leads to a point above highwater level when the carbureter is Yused .upon an automobile orsimilarmachine designed to ford streams. A chamber 46 is `formed upon theexterior of the body 1 under the nipple passageway 2 thereof, andanipple 47gcommunicates at one end with the interior of the said chamberand. at itsother end with the space inclosed by the ring 23. The saidnipple 47 holds the said ring against rotation. A butterfly valve, not

` shown, but whose stem is indicated at 48, is

locatedin the passageway 2, and the carbureter may be primed bymanipulating said butterfly valve in the usual manner. A screen 42 (bestseen in Figs. 1 and 2) is located under the lower end of the tube 11 andis adapted to prevent large solid bodies from entering the tube 11 withthe oil. Nipples 49 are mounted at the sides of the body 1 and have theinner ends of their -passageways in communication with the upper end ofthe passageway 22as illustrated in Fig. 2 of the drawings. It is throughone or the other of these nipples that the gasolene is admitted into thechamber 13, the gasolene flowing through the said nipple, thence throughthe passageway 22 into the said chamber. Two of the nipples are providedin order that the carbureter may be used at either side of a machine.The nipple which is not in use Yis closed by a cap, as illustrated inFig. 2.V As the gasolene accumulates in the saidY compartment the float16 rises and the arm 17 operating against theV stop 20 will move thestem 18 and close the valve head 19 against the seat 21 until thegasolene in the chamber 13 assumes a normal level, when the said valvehead 19 will fall away from the seat 21 by gravity.

The gasolene which is admitted into the through the registering'openings7 "and 9 fin the tube 6 and the sleeve 8 into the space inclosed by thering 23. Here the fumes will mix with the air justadmitted into thespace inclosed by the ring 23 through the nipple 47 and this mixtureVpasses Vup through the opening 25 in the diaphragm 24 under the ring 27and into the cylinder 29. From the' cylinder 29 the mixture is drawn outthrough the outlet opening 34 at the upper and lower sides of theflattened discharge end ofkthe nozzle 35. Thus Ythe mixture just drawnVthrough the nozzle.

comes out in a thin ribbon incased between upper and lower Ylayers ofvmixture which have been drawn out through the upper.

and lower portions of the yopening "34. Therefore the air and gasoleneis thoroughly mixed in two primary mixtures, Y

and these mixtures are nallymixed before they pass into the enginecylinder.V Y

A handle lever50is fixedto the upper end of the sleeve 8 and isprovidedwit-h a linger '5l which extends down between the arms 43 of thesplit ring 43. One end of the screw 43 is in the path of movement ofthis linger 51. Consequently when the handle lever is turned to increaseor diminish the registering spaces between the openings 33 andpassageway 2 and the opening 34 and passageway 3, the cylinder 29v ismoved longitudinally by means of the cam surfaces 28 and 30, the formerof which is carried by the ring 23 and the latter by the cylinder 29.Therefore the head 41 'of the needle valve will be moved toward or awayfrom its seat and the quantity of gasolene 'admitted into the lower endof the tube 6 will be regulated at the same time that the mixture andair is throttled. Also as the ring 27 will be moved toward or away fromthe opening 25 and the passage of the mixture through the said openingwill bc regulated at the same time that the final mixture is throttled.Also the openings 7 and 9 in the tube 6 and sleeve 8 will be moved outof perfect register with each other and the passage of the gasolenethrough the said openings is thrott-led. The cap 44 not only serves inpart as means for conducting air to the upper end of the sleeve 8, butit also serves as means for preventing the plug 38 from being tamperedwith after the said plug and the valve stem 40 attached thereto havebeen set. By reason of the fact that the said cylinder 29 is closed atits upper end the suction of the engine through the discharge passageway3 will have a tendency to draw the said cylinder down tight against theupper edge of the ring 23. Therefore it will be seen that by looseningthe bolt 43 that the split ring 43 may be shifted in its position uponthe projection 1 and secured in an adjusted position so that the path ofmovement of the cylinder 29 and coperating parts may be regulated, butthe swinging movement of the cylinder 29 andthe connected parts islimited by the arms 42 and the screw 43 carried by one of the said armsso that the extent of movement may be adjusted.

In case the carbureter is used in conjunction with very large engines anarm 52, as illustrated in Fig. 8, is employed. This arm is fixed to theplug 38 and has an end portion which lies between the extremities of thesplit ring 43, but the said arm may move vertically between the saidextremities. By this arrangement a very line and accurate rise and fallof the needle 41 may be accomplished.

This carbureter is so constructed that a hundred horsepower carburetercan be used on a one horsepower engine with the same adjustment of theplug 38, which is largely due to the perfect control that the numerousthrottling points have over the mixture. For instance, when the mixtureis being throttled in its movement through the discharge nozzle 35 it isalso being throttled through the opening 34 of the cylinder 29.

At the same time it is being throttled at the openings 31 and 32, andalso at the openings 7 and 9. As this is being done the opening 25 inthe diaphragm 24 is closed wholly or in part by the plate 27. Also theinlet of air is throttled at the opening 33 and passageway 2, whichmakes seven points at which the elements are throttled. There are twosets of air openings that remain constant, the openings 26 in thediaphragm 24 and theslots in the upper end of the plug 38. Also thedimensions of the passageway through the nipple 47 and chamber 46 do notvary. The nipple 47 is smaller in transverse sectional area than thechamber 46,

and the combined ports 7 and 9 are of greater transverse area when wideopen than that of the nipple 47. Consequently when the ports 7 and 9 arewide open and the nipple 47 being of less area, the gasolene is drawninto the air space under the diaphragm 24 and within the ring 23 and isthreshed into a perfect mixture. The gasolene passes into the air spacewithin the ring 23 through the lower portions of the ports 7 and 9 andthe mixture comes back into the tube 6 through the upper portions of thesaid ports and at the same time some of the mixture goes up into thecylinder 29 through the openings 26 and 25. The passageway through thenipple 47 being smaller than the transverse sectional area of thechamber 46, no gasolene ever goes into the said chamber. When the ports7 and 9 are nearly closed and their combined transverse sectional areais less than that through the nipple 47, no gasolene goes out throughthese ports into the space under the diaphragm 24. Therefore it will beseen that by providing these numerous throttlings a synchronic effectand perfect control of the mixture is attained in a simple and easymanner. This control ranges from a mere leak to wide open position ofthe parts, and to accomplish this it is not necessary to use togglejoints or other mechanisms calculated to be affected by sand, water orother foreign substances.

Having thus described my invention, what is .claimed as new is:

l. A carbureter comprising a body having an air inlet passageway and amixture outlet passageway, a cylinder journaled within the body andhaving an air inlet and a mixture outlet, a tube fixed with relation tothe body, a sleeve xed with relation to the cylinder vand snuglyreceiving the tube, said tube and sleeve having at points between theupper and lower 4ends of the cylinder openings adapted to register, anozzle surrounding the opening upon the sleeve and having a flatteneddischarge end passing through the mixture outlet in the cylinder andhaving its extremity in an arc coincident with t-he arc of curvature-ofthe outer periphery of the cylinder and mans for introducing air and oilinto the tu e.
